      abstract     = {The study of nanoparticle self-assembly has been of
                      interest in the field ofnanotechnology due to their broad
                      range of potential applications. It allowsfor the creation
                      of new nanomaterials with unique properties that differfrom
                      bulk materials. The distinctive properties of nanoparticles,
                      such astheir high surface area relative to their volume and
                      enhanced quantum effects,facilitate the development of new
                      technology across various industries.However, nanoparticles
                      must be organized into ordered structures to be ableto
                      exhibit their characteristics in practical applications.
                      Therefore, producingstructures with long-range ordering is
                      needed to utilize the functionalproperties of nanoparticles.
                      To achieve this, nanoparticle self-assembly is away to
                      arrange nanoparticles into defined structures using
                      interparticle andparticle-substrate interactions.In this
                      thesis, the self-assembly of silica (SiO2) nanoparticles
                      with a diameterof 200 nm into ordered monolayers on a
                      silicon substrate is investigated.Silica nanoparticles in
                      particular offer great tunability of their
                      physical,chemical, and optical properties, in addition to
                      their low toxicity andgood biocompatibility. They can be
                      derived from biomass, making them notonly cost-effective but
                      also environmentally friendly. Fabricating monolayersfrom
                      silica nanoparticles allows them to serve as a modulating
                      substratefor the subsequent deposition of thin films,
                      thereby enabling the tuning ofproperties such as optical,
                      mechanical, and magnetic characteristics. Forthis, an
                      improved version of drop-casting is used to fabricate the
                      monolayersthat includes the addition of stearyl alcohol to
                      the nanoparticle dispersion.Then, a drop volume series
                      investigation is conducted to determine the idealdrop volume
                      as it is a key factor in the self-assembly process. This is
                      followed by an additional heat treatment step to improve the
                      monolayer quality.The structural characterization of the
                      SiO2 was done by Scanning ElectronMicroscopy (SEM) to obtain
                      local information, and by X-ray Reflectivity(XRR) and
                      Grazing-Incidence Small-angle X-ray Scattering (GISAXS)
